To all whom 'it may concern:

Be it known that I, FRANK A. NIEBERDING,

a citizen ot the United States, residing at lleveland, in the county of Cuyahoga and State of ()hio. have invented a certain new and useful Improvcnwnt'in Stoves, of which the following is a full, clear, and exact dc provision .of a construction W ereby the .heated air may be distributed in such man- 11er as to secure high efficiency in heating the apartment in which the heater or stove may be located; the provision of a coperating construction of heater and housing by means of which the former may be conveniently applied to and removed from the latter; the provision of an efficient construction for equalizing the circulation of the products of combustion through the air heating` fines; also the provision of a convenient construction whereby the heater may be converted from a direct to an indirectdraft stove. and vice versa.

Generally speaking, the invention may be deiined as consisting of the combinations of elelnent-s and parts embodied in the claims hereto annexed and illustrated in the drawings forming part hereof, wherein- Figure 1 represents a. substantially central vertical sectional view through a heater constructed in accordance with my invention; Fig. 2 a vertical sectional View corresponding substantially to the line 9.--2 of Fig. 3; Fig. 3 a transverse sectional view on the line 3 3 of Fig. 1; Fig. 4 a perspective view of t-he draft-equalizing plate for the tlues and the draft-adjusting plate coperating therewith; Fig. 5 a sectional View corresponding to the line 5-5 of Fig. 1; and Fig. a similar view corresponding substantially to th-e line G--t of Fig. 1, the cover plate for the draft-equalizing and adj usting chamber being broken away.

Describing the parts by reference characters, 1 denotes the tire place openin of a chimney and 2 the vertical flue of said c imney. The chimney and fire-place opening will be of the ordinary or` standard type. With this tire-place opening I employ an air-circulating housing having a frame, the frame being adapted to fit around the edge of the chimney opening and being preferably se arable from but secured to the housing, W1th a heater and ornamental front construction removably carried by said frame. lhe housing is preferably of sheet metal and comprises a rear wall 3, side Walls 4, a bottoln Wall 5, top Wall 6, and a frame to which the outer edges of these Walls are secured, said frame being adapted to fit the chimney opening and bear against the face of the chimney breast.

7 denotes the frame, and the outer edges of the sheet metal housing are conveniently secured to said frame, as by means of bolts 8. The frame is ireferably an inte ral casting and is provi ed in the top an in both sides thereof wit-h a groove 9 lfor the reception of packing material 10, such as asbestes, said packing material enabling the frame to form a tight joint with the chimney breast. The-frame is of such size that the bottom of the same may rest upon the floor or tiling of thetire place with the top en- The side walls 4 of the housing are shown as flaring outwardly from the rear Wall 3, While the upper wall 6 is inclined upwardly from said rear Wall to the upper portion of the frame 7. The housing is provided with a suitable discharge opening 11 at the central -portion thereof and at the junction of the top and rear walls. This opening 11 is the outlet opening from a flue collar which is carried by the housing. This flue collar is preferably an integral casting 12 which is secured tothe top and rear walls of the housing, as shown by bolts 13.

Each side member of the frame 7 is provided at a short distance below the top thereof with an inwardly extending projection a 16, The purpose of these projections and sockets will bc explained hereinafter in connection with the heater proper.

The `heater which I employ in connection with the aforesaidhousing comprises a' fire box, which may be adapted for any kind of fuel, the form illustrated herein being shown as employing gaseous fuel. Suitably connected to the lire box is a lateral series of lues each having downwardly and upwardly extending ducts arranged to permit either a direct or an indirect circulation of gases. At the top of these fines there is located a chamber containing a plate which is arranged to equalize the draft through the flues and having means whereby the outlet from the chamber into the flue collar may be adjusted to accommodate the heater to the draft conditions in the chimney. rl`he lire box shown herein comprises a tire back 17, which is preferably an integral casting extending from the bottom of the heater to the top thereof and provided in the upper rear portion thereof with a plurality of discharge openings 18. The rear surface of the lire back is preferably corrugated, as shown at 19, and the upper edge of said lire back is provided with an upstanding flange 2O for the upper end of a front frame to which reference will be made hereinafter. The lower end of the tire back is provided with a kforwardly projecting flange 21`which is adapted to receive the inner or rear edge of a bottom plate 22, the front or 'outer edge of which is supported by the lower inturned end 23 of the frame 24. The frame 24 is bent inwardly above the bottom and forms a seat for the lower ends of the doors 25, being provided with an upstanding flange 26 against which the inner edges of the bottoms of said doors abut. The frame 24 may. have its opposite ends secured to the sides of the re back.

27 denotes a plate which extends substantially parallel to the bottom plate 22 and is spaced therefrom to provide an air-receiving chamber 28 wit-h the former platethe fire back and the frame 24, the frame being provided with openings'28* for supplying air to said chamber. The outer edge of the plate 27 may be conveniently supported from the inturned edge ofthe frame 24, and the said plate is provided with openings for the upper ends of burners 29, the mixers whereof are located within and receive their air from chamber 28. The upper ends of the burners project into the. tire box beneath a grate 30, which is shown as provided with artificial fuel 31.

The frame 32 extends across the top of the fire box and is provided with a flange 33 adapted to bear against the flange 20 and with a forwardlyprojecting seat 34 below the former ange, for a purpose to loe hereinafterdescribed. The lower end of the eBase? frame. 32 forms an abutment lfor the upper ends of the doors 25, which doors are hinged each to a vertically extending frame plate 35, as shown at 36. Each of these frame plates, as will appear more, particularly fromv Fig. 3, is provided at its inner edge with an inwardly projecting t1ange'37 adapted to tit within a corresponding outwardly Iprojecting flange 38 carried by the front edge of the tire back. The outer edge of each plate 35 rests in a seat 39 formed on each side member of the frame 7. rl`he lower end of each plate 35 is provided with a downwardly and outwardly projecting pintle 41 which is adapted to enter the socket 16a formed in each projection lv carried by the side members of the frame 7, as indicated more particularly in Fig. 2. The frames 24, 32 and 35 are preferably an integral casting for the front of the stove or heater.

Reference has been made to the iues with which the tire box communicates. A lateral series of four such fines/is shown, each flue consistingvof a pair of vertically extending' ducts 42 and 43 separated from the top to Ia point near the bottom thereof by a partition and each flue communicating near its upper end with one of the fire box outlets 18. Each completeflue is preferably made of two complementary sinuous castings, adapted, when placed together, as shown in Fig. 3, to form a complete flue having a downwardly extending duct 42 and an upwardly extending duct- 43, said ducts being separated by means vof a partition conveniently formed by ribs 44 projecting from one casting toward the other and adapted, when said castings are fastened together, to form a complete partition. Each casting is provided at the enlarged front portion thereof with an outwardly projecting rib or wing 45. Each double flue is supported near its lower end from the -lire back 19, as by means of lugs 46 carried by said fire back and a bolt 47 extending through each of said lugs and 'through corresponding lugs 43 on the flue sect-ions. (See Fig. 3). The wing 45 on the outer surface of each outermost flue of the series is in substantial contact with a side wall 4 of the housing, and the other ribs of said flues are in virtual engagement. with each other, whereby an lair space 49 is provided between said ribs 45 and the fronts of the tlues and the tire back 19. while an air space 50 is formed between said ribs and the back wall 3 of the housing. Near their upper ends the lues are provided each with a collar 51 adapted to register with an outlet opening 13 in the tire back. The upper ends of the fines are flush with each other and are provided each with a neck 52 adapted to receive a short collar 53 projecting downwardly from the vertical walls 54 of thelower section of the draftre ulat'ing chamber and said section is provi ed with a bottom plate 53 having o en ings registering with the up er ends o` the flues. This section is rovi ed at the rear central portion thereo with a rearwardly extending flange or lip 55 which is adapted to engage the inner end of the flue collar 12. The 11p 55, aswill appear more particularly from Figs. 5 and 6, is of the same lateral extent as the lue collar 12.

56 denotes a platewhich rests on the top of the front and back walls of the section 54 and is of substantially the same length as the lip 55, being rovided at its rear end with a downward y rojecting flange 57 adapted to lit against t e lip 55 and having at eachl end thereof a short projection 58 adapted to form a corresponding short extension of the upper edge of the section 54. The plate 56 covers the upper ends of the twoinnermost or central lues of the ser1es, leaving the ends of the outermost 4l'ues uncovered, as indicated in Fig. 6. The

purpose of this construction is to e ualize the draft through the fines. lVith t 1e arrangement of flues shown and described herein, there is a tendency for the draft to be strongest .through t-he centrally arranged flues. The provision of the plate 56 checks the draft through these flues while leaving the draft comparatively free through the outermost flues, thereby equalizing the draft through all of the flues. The plate 56 is provided at its central portion with serrations 59 and with a rib 60 on each side of said serrations. j

61 denotes a cover section for the section 54. This cover section is provided with an integral flue collar 62 closed at the top and. sides and open at 'the bottom to coperate with the lip 55 to form an outlet connection .from the position of the chamber included between said cover section and the plate 56 and the flue collar 12. The cover 61 comprises a to-p and downwardly. projecting ends and' front, said ends and front cooperating with the upper end of thesection 54 to form a chamber therewith.

VVit-hin the upper chamber 62", formed between the cover 61 and the plate 56, there is 4located a chimney-draft regulator 63. This regulator is shown as a plate which extends across the space between the cover and the plate 56 and is provided with an operating handle 64 extending through an opening in the cover. The lower end of the plate 63 is a lip 65 adapted to engage the serrations 59, and at the end of said Serrat-ions a stop 66 is provided. As will `be seen from Figs. 1 and 6, the central portion of the cover is projected upwardly as compared with the ends thereof. and this upwardly projected portion 67 extends laterally beyond the flue collar 62. The plate i 63 is provided in its lower edge with notches 63 adapted to receive the ribs. 60, and said plate is of slightl less length than lthe width of Vthe ycol ar 62. There is thus formed between the ends of the plate 63 and the sides of the collar 62 passageways, indlcated by the 'arrows 68, for the passage of the. gases into the flue collara 12 and thence into the chimney. By moving the plate 63 Itoward the neck 62, the passageway at each side thereof will he restricted, pl'lhile by moving it in the op insite direction,

e stalling the heater in a fire place, it is only necessary to adjust the plate 63 by the handle to secure proper draft conditions, after which the Vheater will operate with the best eliiciency with reference to the chimney to which it maybe applied. l

Belowy the plate 56 is located a slide 69. This slide rests on the bottom plate 53a of the section 54 and is adapted to cover the upper ends of the ducts 42 or 43, according to the position in which it is placed by its handle 70. When in the position shown in Fig. 5, a direct draft is established between the lire box and the upper ends of the ducts 42; when in the position shown in Figs. 1 and 6, this direct draft is cut off and it is necessary for the gases to pass down the ducts 42 and up the ducts 43, as indicated by arrows in Fig. 1.

It will be understood that the fire box, the flues, the chamber carried at the upper ends of the iues, neck 62, plate 63 and plate 69 lwill be all connected to ether. Under these conditions it will be on y necessary to insert the pintles 41 into the recesses in the projections 16 and tilt the heater upwardly and rearwardly on these pntles, to bring the neck 62 into the flue collar 12. The center of gravity of the heater being at the rear of the pintle 41, the heater will be tirnily supported in place by its bearings on said pintles and on the collar 12."

Above the front of the heatcr'there extends an upper open-work front 71, which may be secured to side members 72. The front 71 projects outwardly from the seat 34.- which is formed therefor on the top of the frame 32. The side members 72 are each provided with a hook 73 having a beveled face 74 adapted to coperate with the beveled face 15 of a lug 14. The front member 71 is providedwith vertically spaced lugs 7 5, 76 for the reception of the front end of a plate 77 which extends transversely of the front and is inclined downwardly from front to rear. At its ends, the plate 77 is provided with forked projections 78 by means of which it may be bolted to the side frames, as shown at 79. The central portion of the plate 77 is provided with a depression 80 which is adapted to receive the outwardly projecting portion of the handle 64 by which the plate 63 is adjusted. This assageways will be en arged. In inprevents vthe plate 63 froml tilting and enables it to close the vertical space between 67 and 56." f l Below the plate 77 there is located an -angle lever 81, said lever being conveniently pivoted to a projection carried by the cover end of the front 71 is ,provided with a suitable number of projections 85, which are adapted to receive a downwardly projecting ange 86 on a cover or sub-mantel 87 the rear edge'of which rests'upon a suitable seat provided on the frame 7.

rlhe arrangement of the inclined plate 77 causes the air which passes upwardly through the passageway 49 formed between the rc back and fronts of the lues and ribs to be discharged into the room `below the top 87 of the frame, while the air which passes upwardly through the housing between the rear wall thereof and the rear of said flues and the aforesaid ribs passes mainly above said inclined plate. By this means, an efficient distribution of heated air is secured and the overheating of the cover or sub-mantel 87 is prevented.

For the purpose of securing the housing within the lire place or chimney opening, the followingconstruction isprovided: The rear wall of the housing is provided with a suitable number of apertures 88, said apertures being preferably located one near each corner of said wall. Spikes 89, each having near the outer end thereof'a threaded aperture 90, are driven into the chimney in such position that the threaded aperture in each spike will aline with an' aperture 88 in the l rear wall. The apertures 88 in the rear wall are of materially greater diameter than the apertures in the spikes, and each aperture 88 is lprovided with a washer 91, which is of considerably greater diameter than said.

aperture. A screw 92 is carried by each washer and projects through the same and The construction described .-provides means whereby the screws may-be adjusted so as to vbe threaded into the spike apertures'without interfering with thevcirculation ofthe -air through the housing. 'A
